I'm in silver now, what can I improve on?

Hi there everyone, I am I top/mid main (mainly darius and viktor top and mid respectively) and I have climbed to silver. Now I know it's preseason and rank doesn't really matter but i'm going to use it as a way of telling about where my skill range is. So I am in silver V, 72 LP (I wouldve gotten into my promos but I got a feeding afk troll on the last game needed to get into my promos) And I mainly focus on things like CS well: get 100 at about 15 minutes Ward: Don't have 2 in my inventory Builds: get defensive things a bit earlier if needed Kills and staying safe: knowing when you can do what CS: Now I usually focus on making sure my CS is good every game, even though I think for about my skill range I should be okay, as I usually have the best or second best cs in the game. Warding: Now while I ward, I could get more than 1 control ward in games, and ward in more optimal spots. Builds: Now I usually get the same exact build, but I change the order of it, although that isnt always the case Kills and staying safe: As Darius, I usually go really aggressive and it works, but I can mostly tell when I need to stay safer Now I know there is ALOT more to the game, but from what i've told you, what should I focus on? I know it might be hard to tell since there isn't any live gameplay, but if I had something to focus on I would feel like I am actually improving lol.
